Long ago, when BBC1 was still a family channel that showed children’s programmes at lunchtime, there was a colourful animation about a character called Mr Benn.

Mr Benn loved dressing up. Every day he went to a fancy-dress shop, where he tried on a new costume — clown, wizard, astronaut, cowboy — and had an adventure, before returning to his mundane life in his suit and bowler hat.

I want to see a remake with Dr Lucy Worsley. No one since Mr Benn has enjoyed dressing up so much.

Historian Dr Lucy Worsley dressed as Elizabeth I for British History’s Biggest Fibs on BBC4

As long as she’s being Grown-up Lucy, in her smart dresses and severe blonde bob, she’s a scholarly and respectable presenter. But let her don a ruff or a bustle, and her eyes glitter with mischief.

British History’s Biggest Fibs (BBC4) saw her pull on a yeoman warder’s finery at the Tower of London.

The effect was as intoxicating for her as three swift glasses of white wine at the historians’ office party. Goodbye decorous Dr Worsley, hello Louche Lucy.

In the show, Dr Lucy tried to debunk mysteries of the Wars of the Roses – but it was confusing

Eyeing the chief Beefeater, she told him saucily: ‘I think I might have a better codpiece than you.’ And while the poor man was trying to think of an answer to that, she added: ‘Let’s discuss our chests.’ Evidently she likes a man in uniform.

When she wasn’t flirting with guardians of the Crown Jewels, she was debunking some of the myths of the Wars of the Roses.
